Title: Optical disk player, optical pickup device and optical disk playing method
Inventor: ARAI NAOYA
IPC: G11B7/00
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To correct a reproducing signal waveform according to inclination by accurately detecting the inclination of an optical disk. SOLUTION: A photodiode provided in a hologram laser in an optical pickup unit 100 detects a sub-beam using a position having a fixed shift in a tangential direction holding the information track of an optical disk as a beam spot. An inclination error signal generation unit 110 detects the inclination of an optical disk OD by taking a difference between two signals generated by the photodiode of the hologram laser detecting a sub-beam. The optical pickup unit 100 reads the optical disk OD to reproduce an RF signal, and sends this to a waveform equalizing unit 120. The waveform equalizing unit 120 inputs the RF signal to a transversal filter capable of changing a correction characteristic according to the inclination of the optical disk OD detected by the inclination error signal generation unit 110, and corrects the waveform.

Title: Fluid imaging method by mri device
Inventor: TAKIGUCHI KENJI
IPC: G01R33/32
Filed: 1990-11-30
Abstract: PURPOSE:To extract a fluid part by one time of measurement at a high speed by separating two kinds of signals which are alternately generated by the impression of lead out gradient magnetic fields repeating the inversion of amplitude and vary in nature with respect to flow, thereby obtaining two sheets of images; an image in which the velocity component of fluid is attenuated and an image in which the velocity component of the fluid is corrected. CONSTITUTION:The echo signals S1 which are stressed in phase change by the velocity component and the echo signals S2 in which the phase change by the velocity component is corrected are alternately generated by continuously impressing the lead out gradient magnetic fields repeating the inversion of amplitude. The signal change in the sampling time direction of the individual echo signals indicates the position information in an (x) direction and the signal change in the respective repeating directions of the S1, S2, indicates the position information of a (y) direction and, therefore, the images are reconstituted discretely by making Fourier transform in both directions with respect to respective data strings. The resulted 1st image is the image in which the signal is attenuated by the velocity component of the fluid and the 2nd image is the image in which the influence of the velocity component of the fluid is corrected. The region 8 where a blood vessel 7 crosses is determined as a selection region and the 1st image and the 2nd image are subtracted, by which the image of only the blood flow is obtd.

Abstract: PURPOSE:To lighten the extent of satellite weight by setting up at least two satellites on a geosynchronous orbit in making them apart as far as more than a range of 18 degrees, and when either has entered the sun shadow of a solar eclipse, making it so as to use another satellite. CONSTITUTION:Both first and second satellites 1, 2 with a certain transmission on a geosynchronous orbit are made up of having a body 3 and a solar-cell panel 4 each. An interval between these first and second satellites 1 and 2 looking from the earth is set to such a position as separating as far as 18 degrees. Accordingly, when the first satellite 1 has entered the sun shadow of a solar eclipse 10, transmission operation takes place after being selected to the second satellite 2 out of the range of the sun shadow 10. These satellites 1, 2 will not enter the solar eclipse at the same time. In sunshine, these satellites 1, 2 are used as a backup flight model with each other. Therefore the loading of battery with capacity necessary for maximum required power during the solar eclipse becomes disused, thus satellite weight is reducible.
